superfine cas 7440-57-5 nano Au powder gold nano powder
Gold nanoparticles dispersion is prepared by dispersing 20nm or even smaller gold nanoparticles into water solution. The preparation will end up with uniform neutral solution with stable color. The gold nanoparticles solution appears to be faint red not golden brown. The gold nanoparticles solution appears to be azury when in condensed state by adding other substance. The solution is edible for human beings and totally safe for skin contact. Like silver nanoparticles, Au nanoparticles are resistant to antibiotics.

Living daily commodity, such as food, beverages, nano-gold soap, toothbrushes, all kinds of beauty mask etc...
Storage Conditions of gold powder
1. Au water dispersion should be prevented from sunlight. 2. The product is for research and development purpose and the user must be a professional person (This person must know how to use this product.) 3. Nanoparticle dispersions are suspensions of nanoparticles in water. These dispersions can be used as-is, or diluted with suitable (compatible) solvents. Nanoparticles in dispersions can sometimes settle upon storage, in which case they can be mixed (shaked up) before use.
